How to Stop Microsoft Word from Automatically Converting PDF Files

Adam Davis Oct 7, 2026 870 views

Question details

The user wants to prevent Microsoft Word from automatically converting PDF files into editable documents when opened, as this damages form layouts and text formatting.

Product: Microsoft Word
Device & OS: not provided
Scenario: Opening a PDF file directly from the computer by double-clicking it.
Observed behavior: Microsoft Word launches and automatically converts the PDF into an editable Word document, resulting in overlapping text and compressed layouts.

Before you start

Before proceeding, ensure you have a dedicated PDF reader installed on your computer, such as WPS Office or Adobe Acrobat Reader, so you have an alternative application to open your files.

Solution 1Recommended

Change the Default Windows Application for PDF Files

Reassign the .pdf file extension to a dedicated PDF reader so that double-clicking a PDF opens it natively without triggering Word's conversion process.

By default, if Microsoft Word is set as the primary application for PDF files, it will automatically use its 'PDF Reflow' feature to convert the document into an editable format upon opening. Changing your operating system's default app settings prevents this.

Locate a PDF File

Navigate to the folder on your computer that contains any standard PDF file.

Open the Application Menu

Right-click on the PDF file, hover over 'Open with' in the context menu, and click on 'Choose another app'.

Select a Dedicated PDF Reader

Scroll through the list of available applications and select your preferred PDF reader, such as WPS Office or Adobe Acrobat Reader.

Set as Default

Check the box at the bottom that says 'Always use this app to open .pdf files' and click 'OK'.

Change the Default Windows Application for PDF Files

Default App Updated: Your PDF files will now automatically open in your chosen PDF reader with their original layout completely preserved.

Solution 2

Open PDF Files Directly from a PDF Reader

Bypass Microsoft Word completely by opening your PDF files from within your dedicated PDF application instead of double-clicking them from a folder.

Frequently Asked Questions

Why does Microsoft Word convert my PDF instead of just opening it?

PDF is not a native format for Microsoft Word. When Word is forced to open a PDF, it runs a feature called PDF Reflow, which attempts to extract the static text and images and rebuild them into an editable Word document format. This process frequently causes layout shifts and overlapping text.

Can I stop Word from converting PDFs if I open them directly from inside Word?

No. If you use the 'File > Open' command inside Microsoft Word to open a PDF, it will always trigger the conversion process. To view a PDF exactly as it is, you must open it in a dedicated PDF reader application.

How can I edit a PDF file without ruining its layout?

To safely edit a PDF without risking layout damage, you should use a dedicated PDF editor rather than a word processor. Tools like WPS PDF allow you to directly modify text, images, and fillable forms within the native PDF structure.
